So while i was toying around with my new computers in Minecraft, I was kinda annoyed that I had to tell the computer which sides he may use for networking each time I'd reboot. So, I spent the last two evenings writing this little script which handles that for me.
I don't know whether somebody else already wrote that kind of thing, I just hope not.
I wrote this for RedWorks, but as long as CraftOs also has an autorun folder thingy it should smoothly.

REQ: - Str Utils Api
CODE:
Spoiler
local time = 5 -- this is the time the program will wait and display you the results before
local dir = "/etc/" -- this is where config files will be stored
local ports = "ports" -- and this the name of the actual config file
local content = "front, falsenback, falsenleft, falsenright, falsentop, falsenbottom, false" -- I guess the pattern should be clear
function main ()
file_ports = io.open (dir .. ports, 'r')
line = file_ports:read ('*l')
while line do
port = {}
for k, str in pairs (StrUtils.seperate (line, ', ')) do
table.insert (port, str)
end
if port [2] == 'true' then
print ('Open port: ' .. port [1])
rednet.open (port [1])
elseif port [2] == 'false' then
print ('Close port: ' .. port [1])
rednet.close (port [1])
else
print ('Something's wrong with your fire wall setting.')
end
line = file_ports:read ('*l')
end
file_ports:close ()
os.sleep (time)
end
function setup (mode) -- mode describes whether /etc exists or not
function make_config(file)
file_ports = io.open (file, 'w')
file_ports:write (content)
file_ports:close ()
end
if mode then
make_config (dir .. ports)
elseif not mode then
fs.makeDir (dir)
make_config (dir .. ports)
end
end
if fs.exists (dir .. ports) then
main ()
elseif fs.isDir (dir) then
setup (true)
main ()
else
setup (false)
main ()
end
Place this in your autorun directory (/rom/autorun in RedWorks) and it should work.
On boot it will check whether the config file exists and if not create them from the defaults in the car $content, after that it'll look into the config file and open the appropriate sides for networking.
Any comment on this is appreciated as this is actually my first program ever written in Lua.
